The Business Direct Hotel caters to people who travel for different types of business trips. On Saturday night there is not a lot of business travel, so the ratio of the number of occupied rooms to the number of unoccupied rooms is 2:5 . However, on Sunday night the ratio of the number of occupied rooms to the number of unoccupied rooms is 6:1 due to the number of business people attending a large conference in the area. If the Business Direct Hotel has 432 occupied rooms on Sunday night, how many unoccupied rooms does it have on Saturday night? hoped i helped :)

360 unoccupied rooms on Saturday night

Explanation:

There are 432 occupied rooms on Sunday.

The ratio of occupied to unoccupied on Sunday is 6:1. This means there are 6 times as many filled rooms as empty ones.

Divide 432 by 6 to get 72. So there are 72 empty rooms on Sunday.

In total, there are 432+72 = 504 rooms

On Saturday night, the filled room to empty room ratio is 2:5. This means for every 2 rooms taken, 5 are empty.

Let x be some integer such that 2x and 5x represent the filled and empty room counts.

2x = number of filled rooms

5x = number of empty rooms

Since we found earlier there are 504 rooms total, this means

2x+5x = 504

because we're simply adding the filled room count (2x) and the empty room count (5x) to get the total number of rooms (504).

Solve for x

2x+5x = 504

7x = 504

x = 504/7

x = 72

Now use this to find the following data for Saturday night

As a check, 144+360 = 504, which confirms we have the right answer.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
